My Coleman Mach AC compressor runs non-stop right now regardless of what the thermostat is turned to. I had it set to auto at 72 degrees then woke up at 4am to a 62 degree camper. Turned off the thermostat to find that the compressor wouldn't shut off.
I turned it off at the breaker and let it sit for a few hours. Then the compressor turns on as soon as you flip the breaker back on. Furthermore, the low setting on the fan doesn't work, only the high setting on the fan.
I did some research and found that sometimes it could be a problem with the thermostat on the wall having a short with the yellow wire that goes to the compressor. So I replaced the thermostat with the same thing. No change.
Could this be the controller board on the unit or a relay. Do you know of a good video that will help me check continuity to diagnose this?
My feeling that I have lost control of the compressor and low fan that I lean toward the controller board but I'm not sure.
Our local shop is scheduled a month out and we have a trip planned in a week with a family of five in the middle of summer. You get my drift.
Any thoughts would be appreciated.
Thank you.
